First day of Endocrine! This daily doodle features a VLDL, one of the five major groups of lipoproteins (chylomicrons, very-low-density lipoprotein, low-density lipoprotein, intermediate-density lipoprotein and high-density lipoprotein). VLDLs are assembled in the liver from endogenous triglycerides, cholesterol, and apolipoproteins (white globs of proteins sitting on the surface). They are converted in the bloodstream to low-density lipoprotein (LDL).

TAGs remind me of jelly-fish… To note, they would not be floating freely outside the VLDL like they are in the doodle. They are very hydrophobic, which is why they hide inside the VLDL.

Lectures: 1) Lipoprotein Metabolism 2) Molecular Basis of Inherited Disorders of Plasma Lipoprotien
